and more particularly to an improvedvalve meansl for a vented tap of thecharacter disclosed in my copending4 application for Letters PatentSerial Number 661,233,- filed March 17, 1933.

An object l.of my invention is to provide a new and novel form of ballvalve for a dispensing' tap or other fluid conduit.

Another object of my invention is to provide a new and improved valvemeans for a tap having a controlledvent.

Other objects and advantages of my invention will be in part evident tothose skilled in the art, and in part pointed out in the followingdescription, taken toge er with the accompanying drawing wherein th isshown, by way of illustration and not of limi tion, a preferredembodiment thereof. g

In the drawing; Figure 1 is a perspective view of a tap constructedinvaccordance with my invention,

Figure 2 is' alongitudinal sectional view oi the tap illustrated inFigure 1, showing the position of the parts whenrthe tap valve is open,

Figure 3 ils a view similar to Figure 2, showing the position of theparts when the tap valve is closed,

Figurek 4 is a transverse sectional view taken,

4 tion for Letters Patent. 'Ihe tap illustrated has a body portion 10with a vent opening 11 in its top and a spout`12 at its lower side. Atthe base of the body portion 10 there is a flange 13 which A is adaptedto engage a mounting gasket, and beyond the ange 13 the tap has a cutter14 and a threaded portion 15, by means of which it can be attached to ametallic container.l These latter features are fully described in mycopending ap- :nlication and form no part of the present invenion. y

Upon referring to Figures 2 and 3 of the draw- "ing, it willbeseen thatthe body portion 10 has an A inwardly tapering bore 16, into which atapered valve carrying and operating member 17 projects. The valvecarrying and operating, member 17 has a handle 18r by means of which itcan be rotated and it is held in the body portion 10 by a snap ring 19.lA. packing gasket 20 is .interposed'between the end of the body portion10 and a ange 21 upon the member 17,-for the ing the outer-end of thetap.

purpose of seal- A The valve carrying and operatingmember 17 has a port22 that is adapted to align with the spout 12 when the member 17 is inits open position, and Vdirectly opposite the port 22 it has a pocket23, into which a vent controlling ball valve 24 may repose when themember 17 is in its closed position. vThe ball valve 26 is located in anopening 27 in the' side of the member 17 and is adapted to roll into andout ofengagement 'with a valve seat 28, of rubber or the like, mountedat the inner end of the spout 12.V As shown, the valve seat 28 isrecessed in the end of a lining tube 29 that is pressed into the spout12.

Upon referring to VFigures 4 and 5 of the drawing, it will be seen thatthe valve carrying and operating member 17 has an eccentric groove 30which extends in one direction from-the pocket 23 and partially aroundits outer surface. This groove30, because of its eccentricityQ/,fniovesthe ball valve 24 into andvout of sealing engagement with the ventopening 11, as the valve carrying and operating member 17 is turned toclose and/or open the tap.

Upon referring to Figure 6 of the drawing, it will be seen that themember 17 also has a longi- `tudinally extending groove 31 whichterminates at the pocket 23. The purpose of the groove 31 is tofacilitate an' assembly of the tap. When assembling the tap, the bodyportion 10 is'held with the spout 12 'extending upward and the ballvalve 24 is then placed in the body portion adjacent the vent opening11. The helical spring can now be placed in the valve carrying and conftrolling member 17with the ball valve 26 in the opening 27 at its end.After the latter parts ofv the tap have been assembled together, asabove, the valve carrying and operating member 17 can be inserted intothe body portion 10"by holding the ball valve 26 with the thumb so as tocompress the helical spring 25, as shown in Figure 4 of the drawing. Asthe member 17 is inserted into the body portion'io, the groove 31 willprovide a clearance for 'the-ball valve 24. When the member 17 has beenmoved 'into its final posi- 'metallic container 33,. into which thethreaded portion of the tap has been inserted, it will be evident thatwhen the valve carrying and operating member 17 is in the'positionshown, the contents of the container 33 will be free 'to flow throughthe port 22 and out through the spout 12.

the ball valve 24, adjacent the vent opening 11, will drop down into thepocket 23 and permit air to enter the container through the vent opening11 and a conduit 34 leading therefrom and connecting with the interiorof the container. In order to permit a complete draining of thecontainer 33, the threaded portion 15 of the tap is provided with anAopening 35 which will align with the inside surface of the container.

Now should the valve carrying and operating member 17 be rotated intoits "closed position,

. as shown in Figure 3 of the drawing, the ball valve CII 24 will beraised by the eccentric groove 30 and close the vent opening l1 and theball valve 26 will be caused to roll into alignment with the spout 12,where it will engage the valve seat 28 and close the tap. When `the ballvalve 26 is in this latter position, it will be held firmly against thevalveseat 28 by the helical spring 25 and prevent an accidental valveopening movement of the valve carrying and operating member 17.

While I have, for the 4sake of clearness and in order to disclose theinvention so that it can be readily understood, described andillustrated specific devices and arrangements, I desire to have itunderstood that this invention is not limited to the specio meansdisclosed, but may be embodied in other ways that will suggestthemselves to persons skilled in the art.
